I look flat, but I am deep,
Hidden realms I shelter.
Lives I take, but food I offer.
At times I am beautiful.
I can be calm, angry and turbulent.
I have no heart, but offer pleasure as well as death.
No man can own me, yet I encompass what all men must have.
A man while looking at a photograph said, "Brothers and sisters have I none. That man's father is my father's son."
Who was the person in the photograph?
